What types of gas are used for modifying cars?
Thread Content
Hello everyone: Many taxis on the streets have been converted to run on gas. At gas stations, there are signs indicating both LNG and CNG as available fuel types. So, should cars use LNG or CNG? What is the difference between them? Thank you!
LNG and CNG can be used simultaneously; it is technically feasible. However, L-CNG technology requires high-pressure pumps and high-pressure vaporizers, and such equipment is relatively heavy, so using them in cars may not be cost-effective – therefore, it is not recommended
I haven’t heard of cars being modified for LNG use; however, there are modifications for CNG, in the style of taxis. There are also quite a number of large buses and trucks that have been modified for LNG use. The low-temperature and gas-related equipment required for LNG is quite expensive, so it’s likely not economical to modify cars for LNG use
Thank you. I have one more question: LNG is in a liquefied state when it is refilled, while CNG is compressed gaseous NG during refilling. Is that correct?
Yes, if it’s L-CNG, then it’s a different matter. L-CNG is essentially CNG, only it is produced by vaporizing LNG (liquid natural gas) after pressurizing it; this process takes place at refueling stations. As for why small vehicles do not use LNG as a substitute for fuel, what was said on the third floor is basically correct
